Umbilical arterial (UA) Doppler assessment is used in surveillance of fetal well-being in the third trimester of pregnancy. Abnormal umbilical artery Doppler is a marker of uteroplacental insufficiency and consequent intrauterine growth restriction (IUGR) or suspected pre-eclampsia.
Most women first hear their baby's heartbeat during a routine checkup that uses the fetal Doppler early in their pregnancy. Many ultrasound machines also allow the heartbeat to be heard even before it can be heard with a handheld Doppler. Most women now get an ultrasound prior to 12 weeks. What the Test Does. The fetal Doppler uses sound waves to pick up your baby's heartbeat. How the Test Is Done. You'll lie down and a technician will hold a small probe against your belly. It's safe and painless. Some companies sell Dopplers for use at home. The FDA suggests that you avoid them. Although Dopplers are generally safe, using them too much -- without medical supervision -- could pose risks to your baby.
